Lackan Bay Swell Statistics, Autumn: Surf with Light or Offshore Winds

This image shows only the swells directed at Lackan Bay that coincided with light winds or offshore conditions through a typical northern hemisphere autumn. It is based on 8476 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow represent increasing swell sizes and red illustrates the highest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the biggest spokes, was WNW, whereas the the dominant wind blows from the SW. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 31% of the time, equivalent to 28 days. Expect open water swells to exceed >3m (>10ft) 9% of the time (8 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Lackan Bay is slightly protected from open water swells, we estimate that clean surf can be found at Lackan Bay about 31% of the time and that surf is messed up by onshore wind 25% of the time. This is means that we expect 51 days with waves in a typical northern hemisphere autumn, of which 28 days should be clean enough to surf.

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
